Patented Apr. 21, 1931 UNITED STATES PATENT OFFICE HARRY WAGENFELD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO KEYSTONE ADJUSTABLE CAP CORPORATION, OF PHILADELPHIA, PENNSYLVANIA, ACORPORA- TION OF PENNSYLVANIA APPARATUS FOR; PRODUCING BAND MATERIAL Application filed September 12, 1929. Serial No. 392,108.

, This invention relates to apparatus for producing stiffened band material for hats or caps, particularly caps intended to be used by bakers, waiters and persons generally engaged in the handling and preparation of food products and the like.

Caps of the specific kind referred to are usually made from muslin with incorporated reinforcing or stiffening bands whereto the crown portion, ordinarily of gauze or netting, is attached along the lower edges.

To better expenses in laundering and thereby discourage re-use of such caps, it is essential that the cost of their production be reduced to the very minimum.

With the above end in view, my invention is directed toward enabling production of band material of the aforementioned sort more rapidly and economically than possible 2 heretofore. In other words, I aim to provide a structurally simpleand efficient apparatus capable of continuously assembling two strips, one of facing muslin for example and the other of paperor other suitable stiffening, and incidentally applying adhesive, pressing the strips together and making such folds as may beedesirable to efiect perfect consolidation with predetermination of the required stability in the finished product.

Other objects and attendant advantages of this invention'will be'manifest from the'detailed description which follows in connection with the attached drawings, wherein Fig. I is a plan view ofmy improved band producing apparatus.

Fig. VI is a detail section, taken as inclicated by the arrows VI-VI in Fig. I illustrating the-folding'means and, v I p Fig. VII is a detail section, taken as indicated by the arrows VII-VII in Fig. II, transversely of an ironing means formmg a part of the apparatus.

As herein delineated, the band producing apparatus of my invention comprises ahousing 9, which, in its lower part, affords space for two supply rolls 10,11, respectively, of the stiffening material S and facing material F. These rolls 10, 11 are supported for free rotation in suitable bearings 12 and readily accessible for the purposes of replacement by virtue of access had into the exterior of the housing through an opening 9a in one side thereof. As hereinbefore stated, the facing strip'F may be of muslin, and, as shown in Figs. I and III, is somewhat wider than the paper stiffening strip- S. The cas ing 9 rises to a convenient heightfrom the floor, and further serves as a support for an adhesive applying means comprehensively designated by the numeral 13, the same embodying a shallow rectangular receptacle 14 which is kept filled with paste or mucilage to the level indicated at L in Fig. IV. The cover of the receptacle is made in two sections 15, 16 which are separated by a transverse interval 17 adapted to be occupied by an ad hesive applying roller 18. At opposite sides the receptacle 1 1 is equipped with bearings 19 to rotatively support the roller 18 withthe lower half thereof running submerged in the adhesive.v

En route to the adhesive applying means 13 the stiffening strip S is first passed vertically upward through a slot 20 adjacent the top of the sloping end wall of the housing 9., then around an edge bead 21 formed on the section 15 of the receptacle cover, and then horizontally through a guide 22 on the top of said cover section. To insure contact of the stiffening strip S over asubstantial portion of the roller 18, I provide a pair of fixed depressing rods 23, 24 which are supported crosswise of the receptacle 14 in close roximity to opposite sides of said roller. fter overtravelling the roller 18,. the stiffening strip S is guided through a depressed notch in a transverse scraper 25 formed as an integral part of the receptacle cover section 16, said scraper, in addition to acting as a guide, operating to remove the excess adhesive from the stiffening strip S and to direct such excess back into the receptacle 14. Cooperating with the roller 18 is a stationary supplemental adhesive applying element in the form of a fixed finger 26 which extends upward from the rod 24 around the upper part of the roller 18 and slightly overlaps the strip S at one side. Thus, concurrently with application of the adhesive over the entire bottom face of the stiffening strip S, the finger 26 functions to spread adhesive along an edge margin of the upper face of said strip, as

. clearly shown in Figs. III and IV. After leaving the scraper 25, the stiffening strip S is further directed to travel horizontally above the top of the housing 9 by another guide 27 formed of wire and secured to the op osite end of the receptacle 14.

'e facing strip F, upon leaving the supply roll 11 is directed upward through an o ning in the top of the casing 9 to a guide 2 attached to the end of the receptacle 14 beneath the uide 27 for the strip S, then over a bead 29 formed on the cover portion 16 of the receptacle at the corresponding end. After rounding the head 29, the strip F is directed rearward around another guide 30 on the top of the receptacle cover section 16, and finall forward through a third guide 31; where y the facing strip F is directed to travel horizontally beneath the stiffening strip S incident to further progression synchronously with the latter strip in the apparatus.

Referring again to Figs. I and II it will be observed that the apparatus further comprises a table 32 which at that end contiguous to the housing 9 supports a folding means 33. This folding means 33 is formed, in the present instance, from wire with a lateral notch 34 (Fig. VI) at its upper end through which the two strips S, F are passed so that the longitudinal margin M of the facing strip F extending beyond the stiffening strip S, is folded over into contact with the adhesive coated margin M on the upper face of said stiffening strip, as clearly illustrated in Figs. III and VI. The table 32 further fixedly supports on its top an ironing means comprehen'sively designated 35. This ironing means 35 embodies a main section 36 with an upwardly convexed medial portion 37 that 1 merges with concavities 38 at opposite ends,

said section being made hollow for the accommodation either of an electric heating element, or for circulation of a suitable heating medium conducted thereto through a pipe connection 39. After being brought into superimposed relation and folding of the edge of one over the other as hereinbefore explained, the strips S, F are passed over the top of the main section 36 of the ironing means 35 and incidentally caused to follow the concaved hollows 38 of such section by counter-rounded stationary sections 40 which fit said hollows with provision however of intervening spaces 41 for passage of the composite band, see Fig. VII. Like the main section 36 of the ironing means 35, the complemental sections 40 are made hollow either for accommodation of an electric heating element or for circulation of a heating medium supplied through pipes 42.

The means, designated by the numeral 45 in Figs. I, II, for drawing the two strips S, F throu h the apparatus is mounted on the far end 0 the table 32, and, as shown, comprises a pair of opposing nip rollers 46 which are supported by standards 47, with regulatory provisions at 48 to vary the spacing between them. The two nip rollers 46 are intergeared as at 49, and driven by a belt connection 50 from a countershaft 51 beneath the table 32. This countershaft 51 is in turn coordinated through a belt 52 with a drive shaft 53 suspended in drop bearings 54 from the table top, said drive shaft receiving power through a belt 55 from an electric motor 56, the various pulleys involved in the described transmission system determining operation of the nip rollers 46 at a speed considerably reduced in respect to that of the motor 56. As a consequence of having been passed, while under tension induced by enforced traverse over devious courses and by friction incident to passage through the ironing means 35, the two strips S, F are effectively pressed fiat into intimate contact and consolidated into band form at the completion of the ironing period through accelerated drying of the adhesive.

From the foregoing it will be seen that my improved apparatus is simple in construction and capable of being continuously operated' at very high speeds so that by its aid the band material can be produced very cheaply and expeditiously.

Having thus described my invention, I claim:

1. In apparatus for producing band material of the character described, means for con tinuously feeding a stiffening strip and applying adhesive to one face and along an edge margin of the other face thereof; means for synchronously feeding a facing strip into contact with the adhesive covered face of the stiffening strip; and means for incidentally folding a projecting longitudinal margin of the facing strip over the corresponding adhesive coated marginal edge of the stifiening strip.

2. In apparatus for producing band material of a character described, means for continuously feeding a stiffening strip and a plying adhesive over one face thereof as we as a coating of the adhesive along a longitudinal edge margin of its other face; means for synchronously feeding a strip of facing material into contact with the adhesive covered face of the stifiening strip and means for incidentally folding over an extended longitudinal margin of the facing strip onto the adhesive coated marginal edge of the stiffening strip.

3. In apparatus for producing band material of the character described, an adhesive applying means including a roller adapted to distribute adhesive completely over one side of a continuously traveling stiffening strip and a stationary finger cooperating with said roller to concurrently apply a coating of the adhesive along a longitudinal edge margin at the opposite face of said strip; means for synchronously feeding a facing strip into contact with an adhesive covered face of the stiffening strip aforesaid; and means for incidentally folding an extended longitudinal margin of the facing strip over upon the adhesive coated margin of the stiffening strip.

4. In apparatus for producing band material of the character described, adhesive applying means; folding means; means for continuously drawing two different strips through the apparatus; means for initially directing one of the strips over a separate course for diversion through the adhesive applying means to apply adhesive wholly over one face and along an edge margin of the other face thereof; and means for thereafter bringing both strips into contact with each other previous to the folding over of an extended longitudinal margin of the one upon the adhesive coated marginal edge of the other by said folding means.

5. In apparatus for producing band material of the character described, adhesive applying means folding means ironing means means for concurrently drawing two different strips through the apparatus; means for initially directing the two strips over separate courses for diversion of one of them through the adhesive applying means to wholly coat one face and a marginal edge of the other face thereof; means for thereafter causing said strips to contact with each other incident to presentation to the folding means whereby a longitudinal edge margin of the one is folded over the adhesive coated edge of the other strip en route to the ironing means.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania, this 9th day of September, 1929.
